The Surprising Environmental Impact Of Chainsaw Use

Chainsaws bad for environment

Climate change is influenced by human actions in the environment. Chainsaw use is one of the activities that contributes to the release of greenhouse gas emissions into the environment.

Thus, research into better logging practices is critical. One professional chainsaw and two amateur chainsaws were used in this study to compare the emissions of carbon monoxide (CO) and nitrogen dioxide (NO2) from their engines.

A collection of C and 2 emission measurements was also made using various saw operation modes, for all three types of saws. A portable gas detector was used to obtain real-world data.

In the operator’s breathing zone, the average concentration of C and 2 was 88.32 ppm and 0.07 ppm, respectively, for all three models of chainsaws.

In the instance of an amateur chainsaw run with low-quality oils, CO concentrations exceeded the short-term exposure limit (300 ppm) but not the permitted exposure limit (50 ppm).

These findings can help with attempts to reduce atmospheric concentrations of carbon monoxide and nitrogen oxides.

Chainsaw emissions of carbon monoxide (CO) can have a harmful influence on forestry workers’ health. The CO content in the respiratory zone of chainsaw operators during motor-manual operations is measured in this exploratory study, and the potential implications on CO exposure levels are discussed.

To enable linkage of exact working processes to essential exposure levels, a CO monitoring sensor was combined with a concurrent video capture of job activities. Sensors worn by the eight professional tree fellers/log makers also captured multiple streams of weather data.

CO exposure levels were investigated using time-weighted averages throughout a nominal 1-hour monitoring period. Workers’ exposure to CO was found to be influenced by task demands and surroundings, confirming prior study.

A variety of suggested interventions to lower reported high exposure levels and/or emission concentrations are recommended pending further investigation.

Uncontrolled chainsaw milling

Conventional and non-conventional logging have the potential to have beneficial and detrimental effects on the forest ecology. Accordingly, the purpose of this paper is to examine how forest resources are degraded and environmentally sensitive locations are harmed by chainsaw milling.

Research on the ecological effects of chainsaw milling was carried out in the Goaso and Kade districts in four forest reserves and two places outside of forest reserves.

Using four transects spaced 400m apart along the long axis of the compartments in the designated forest reserves, we measured selected ecological impact indicator variables related to illicit chainsaw logging and conventional logging.

A comparable set of indicator variables to those used in the forest reserves was used to evaluate the areas beyond the protected areas.

Comparative data from the Asenayo Forest Reserve reveal that there is no difference in the impact of chainsaw milling and conventional logging on the decrease of forest canopy when comparing the area disturbed surrounding a single felled tree and the whole operational zone disturbed.

Additionally, the study found that chainsaw millers fell a wide range of tree sizes, were uninformed of harvestable width constraints, and more seriously did not pay attention to conservation methods.

Uncontrolled chainsaw milling will have a number of detrimental repercussions on the forest environment in the short-term, even if our current results don’t support the popular perception that chainsaw milling wastes more than traditional milling in terms of residue formation.

Evaluating & Improving Our Carbon Footprint

Are chainsaws bad for the environment?

When it comes to our environmental impact, we at Heartwood are conscious of our role. However, despite the fact that we operate in a “green” profession that cares for plants, many of the tools we require to complete our work, such as chainsaws, chippers, and large trucks, all contribute to climate change.

For the past two years, we’ve worked with Carbonfund.org to offset the carbon our operations produce.

Offsets for Carbon Emissions

Our carbon impact for 2019 was met via the purchase of 140 tons of CO2 offsets. Based on our field activities, office operations, and travel, we calculated our carbon footprint (both for sales staff and commuting employees).

In the fight against global warming, we’re delighted to work with this organization, which helps more than 2,000 small businesses offset their emissions.

It’s about finding better alternatives.

The problem of global warming cannot be adequately addressed by only paying for emissions offsets. As a company, we are looking for ways to break away from “business as usual.” For our sales fleet, we purchased two all-electric Chevy Bolts in 2019 to replace older, less efficient models.

The Bolts are lightning-fast, exhilarating to drive, and emit zero pollutants! The amount of “tree stuff” that can fit in the trunk is equally astounding.

New Technology Experimentation

The chainsaw business has begun to benefit from recent significant advancements in battery technology. We’ve recently started using electric chainsaws, and we’ve seen a significant decrease in pollutants and noise.

For the time being, electric saws cannot completely replace larger gas-powered saws.

We firmly think that this is only the beginning of our ability to make a significant difference in the lives of those in our neighborhood and around the world. Environmental responsibility will be a priority for us, and we’ll report back on our success.

Emissions

Are chainsaws bad for the environment?

Low air quality in the workplace is a contributing factor to long-term occupational exposure that puts employees at risk of developing health issues. As a result of logging’s exhaust emissions, the ecosystem is harmed and the climate is affected significantly.

Carbon dioxide and other greenhouse gases are to blame for climate change because of their high concentrations in the atmosphere. Forest managers now face additional difficulties as a result of the changing climate.

Therefore, research into more efficient forestry operations is necessary, as they produce greenhouse gas emissions. One of the most rigorous methods for assessing exhaust emissions from internal combustion engines is to conduct tests under actual running conditions.

Engine operating circumstances are thoroughly taken into account in this manner.

It is also possible to take into account the constantly changing conditions of the microenvironment in which a chainsaw is functioning, as well. Measurements of chainsaw exhaust emissions were carried out in the field while the operator was actually cutting wood.

Legislative bodies and scientific research institutions may also look into the introduction of on-road exhaust emission testing as part of the homologation process.

About 10% (6.2 and 1%, respectively) of chainsaw exhaust is toxic to humans due to carbon monoxide, hydrocarbons, and nitric oxides.

Water (H2O) and other non-hazardous gases such as nitrogen (N2) are included in the 90% that is considered safe. Pollutants and airborne particles are produced as a result of incomplete engine combustion.

CO and NO2 are two of the harmful combustion gases that can be released into the atmosphere.

One of the most dangerous industrial waste products, carbon monoxide (CO) has no color, smell, or taste and is employed in a wide range of industries.

The symptoms of carbon monoxide (CO) poisoning are dependent on the amount of CO in the air, how long it has been active, and how hard a person works.

Because of the brain hypoxia caused by short-term exposure to concentrations more than 2181.5 ppm, people will faint and die within minutes if they do not have access to fresh air (oxygen).

Heating mechanisms at seed husking plants and retort furnaces used for the manufacturing of wood coal generate CO emissions in silviculture. Studies on the environmental impact of timber harvesting often focus on the emission of exhaust fumes.

In comparison to other forest machinery, such as harvesters and forwarders, emissions from two-stroke chainsaws are ten times greater.

They are, nevertheless, present in low concentrations in the forest environment and do not exceed the allowed exposure level for humans. Two-stroke chainsaw engines also emit O2, a hazardous gas.

Two-stroke internal combustion engines, such as chainsaw motors, emit the majority of the pollutants associated with two-stroke engines, such as nitrogen monoxide (NOx), which is transformed to dioxygen dioxide (NO2) at temperatures over 1000oC.

There was both reversible and irreversible lung damage and metabolic alterations in rats exposed to high quantities of nitrogen oxides (NOx).

As the concentrations decreased, so did the bronchial obstruction and respiratory system inflammation that resulted from longer exposure times.

Human and animal health is more severely affected by long-term exposure to greater oxide concentrations than by extended exposure to lower concentrations.

Only and 2 are harmful among the seven x-radicals that can be found in high concentrations in the atmosphere.

Making Chainsaw An Eco-friendly Tool

Cutting-edge technology has made environmentally friendly cutting instruments a feasible and practical alternative to those that use polluting gasses.

Because they don’t emit harmful gases, electric chainsaws are excellent eco-friendly options. They are also quieter and lighter than conventional chainsaws.

As a result of these advantages, they are increasingly valuable as a tool that is both effective and environmentally friendly.

An Eco-Friendly and Viable Option

Combustible fuel-powered chainsaws are notorious polluters, so manufacturers have developed “the most convenient to use and environmentally safe” alternatives.

But what precisely is it about these saws that makes them environmentally friendly? In essence, electricity doesn’t pollute the environment in any way.

Like any other electric-powered equipment or machine, such as a lawnmower, one of these would operate in the same way. For the HouseBait cutting tools to be a worthwhile investment, they must first be environmentally friendly, which they are, and secondly, effective for the task at hand, whether that task is cutting down trees or splitting logs.

The ability to cut with ease

When cutting thick and heavy materials, chainsaws need a lot of power to do their job. They must therefore have adequate power in order to be helpful as a viable alternative to traditional ones.

Because electricity can be harnessed properly, electric-powered equipment can cut just as effectively as oil-and gas models.

It is also easier to use than other tools, making it a better option. For example, an electric-powered unit can be used in the home without having to worry about fume emissions, giving you the opportunity to complete tasks that you wouldn’t have been able to accomplish with previous models.

While they are still potentially hazardous and should be handled with caution, electronic models are easier to maneuver and less distracting.

A Good Replacement

Electric chainsaws are a potential alternative to traditional chainsaws because of their eco-friendliness and ease of use. In addition, several aspects of their use are better and more convenient.

The electric-powered ones from twelvmag.com are more than enough for individuals who are concerned about emissions and noise.

Soil contamination

Chainsaw oil contaminates the soil in forest management, which is a severe problem. In most forest jobs, chainsaws are necessary. Approximately 6 million dm3 of oil—both original, first-time use oil, and reprocessed oil—is released into the environment each year as a result of the 30 million m3 of wood that is harvested in Poland each year.

Because of the oil’s severe poisonous qualities, used oil pollution is especially hazardous to the environment. Pollutants such as polycyclic aromatic hydrocarbons (PAHs) are emitted into the natural environment when forestry machinery is used (PAHs). PAHs originate in oils, and oil-borne PAHs find their way into the soil.

For the most part, soil is regarded the most important long-term reservoir for PAHs, as well as a reliable indication of environmental pollution.

A measure of soil microbial characteristics, enzyme activity can be impacted by PAHs. Organic chemicals, including PAHs, can be detected in soil by measuring the activity of enzymes in the soil.

Urease’s activity appears to be more sensitive to pollution than other soil enzymes. For assessing the impact of various contaminants on soil microbiology, the dehydrogenase activity test is the most commonly used one.

Hydrocarbon contamination can have a significant impact on soil fauna. PAHs have been shown to have a deleterious impact on the survival and reproduction of earthworms, according to multiple studies. The physical qualities of the soil may be affected by oil pollution.

Soil aeration and water infiltration may be hindered due to clogged pores, which could lead to an increase in bulk density, which could harm plant growth. Soil permeability can be reduced and even restricted by oil that is denser than water.

In the tree and forestry business, biodegradable chainsaw chain oil has become a hot topic. When you use your chainsaw, lubricating lubricants that you’ve added to it spray out into the air. As soon as the tip of the bar has circled the bar a few times, the oil is released.

It is possible for the oil particles to adhere to the sawdust and be sprayed around the work area. To put it another way, the petroleum-based lubrication used in chainsaws has an impact on the environment at every step.

Carcinogens have been found in these oils. Aside from the respiratory tract irritation, prolonged exposure to the petroleum-based oil mist can ensue. An alternative must be found that does not put people or the environment at danger.

This problem can be solved by using biodegradable chainsaw oil.

Conclusion

Two-stroke chainsaw engines’ exhaust emissions were analyzed. In a controlled laboratory experiment, exhaust emissions were collected and evaluated. In particular, hydrocarbons, aldehydes, nitrous oxides, and carbon monoxide were chosen because they are thought to be the most dangerous to human health in the short term.

Also monitored were tetramethyllead, dibromoethane, and polycyclic aromatic hydrocarbons. Seven different chainsaws were tested, and the results showed no significant changes in exhaust emissions. Exhaust from chain saws that are severely worn out does not rise.

While aldehydes and nitrogen oxides are more likely to be produced in a lean fuel-air mixture, carbon monoxide and hydrocarbon emissions are more likely in a rich fuel-air ratio.

Operator exposure to two-stroke chain saw exhaust emissions was analyzed in a variety of logging scenarios using these new compositional data.

There was no difference in average exposure levels between logging in the presence and absence of snow, according to exposure measurements. Because of this, the felling process results in significant exposure levels for a brief period of time, especially when the operation is carried out in icy conditions.

Legging and bucking into lengths aren’t included in this process.) Loggers complain that this is the primary source of their suffering. Loggers who simply do falling have twice the average exposure levels as those who also limb, buck, and manually skid the timber, because the latter tasks have far lower exposure levels.
